标准摘要
[中文适用范围]： 本部分 IEC 61094 适用于符合 IEC 61094-1 要求的实验室标准传声器和其他类型的测量传声器，描述了确定复声压灵敏度的一种可能绝对方法，该方法基于一种能够在已知声压下（特别是在低频下）产生已知声压的装置，并为低频下的声压测量提供了可重复且准确的基础。所有量均以 SI 单位表示。 [外文原描述]： IEC TR 61904-10:2022 - is applicable to laboratory standard microphones meeting the requirements of IEC 61094-1 and other types of measurement microphones, - describes one possible absolute method for determining the complex pressure sensitivity, based on a device capable of generating a known sound pressure, especially at low frequencies, and - provides a reproducible and accurate basis for the measurement of sound pressure at low frequencies. All quantities are expressed in SI units.
